What reviewers say

Reviewers agree it is an outstanding monitor for creative work, praising its superb image, near-perfect colour accuracy out of the box, built-in colorimeter and very wide port selection. The main complaint is the high price; Tom's Hardware noted the lack of speakers and a headphone jack and the 120Hz limit, and TechRadar and Trusted Reviews found the stand and design plain.
